Got a 2008 Mac Pro 3,1 upgraded and crunching C@H GPU tasks - dual Quad Core 2.8 GHz Xeon processors, OS X 10.9.4, 500 GB 3G SSD, 3 TB conventional HD, 14 GB 800 MHz RAM, and an NVIDIA GeForce GTX 760 clone. 185K RAC. :-)

Took delivery today of what was supposed to be another 2008 Mac Pro 3,1 - dual Quad Core 3.0 GHz processors and an AMD HD 5770 GPU. Was going to add 8 GB RAM, OS X 10.8.5 and another AMD HD 5770 GPU. Shooting for 250K RAC. But, alas, it was a 2007 Mac Pro 2,1 with dual Dual Core 3.0 GHz processors. $#@%^&^$*&%^(&*%^^$%. Won't even run OS X 10.8. Returning that unit to the seller and going back to eBay for more shopping.

But, at least, for now, I am winning!


Good grief 185k rac from a single machine, that's very good! Sorry your 'new' machine wasn't as advertised though!! Sometimes Ebay is very good, sometimes not so much.

C@H RAC on my upgraded 2008 MacPro 3,1 continues to rise and is now over 200k/day. Not bad for a 6-year old box, albeit with some major upgrades. Indeed, each of my three 2008 MacPro 3,1 boxes has a C@H RAC in excess of 190K. Thanks, Slicker, for all of your exemplary efforts in keeping this project running - keep the work coming!

Still trying to buy another MacPro 3,1 on eBay. Have the RAM, HD, and GPU ready to transplant.

But, in the meantime, at least I am winning!

Do they have pci-e slots in them? If so you could really rock the rac with a gpu in each of them.

Message 19789 - Posted: 20 Aug 2014, 12:37:00 UTC

Thanks for the suggestion, Mikey. I have thought about putting multiple GPUs in each box. There are three practical issues. (1) A 2008 MacPro 3,1 has two PCIe x4 slots and two PCIe 2.0 x16 slots. The spacing of the slots is such that you can't fit more than two of the more powerful GPUs (AMD HD 7950, AMD HD 5870, NVIDIA Quadro FX4800, NVIDIA GTX GeForce 680, etc) in a single box, with each GPU occupying a PCIe 2.0 x16 slot. (2) A 2008 MacPro 3,1 provides only two power connections on the motherboard for GPUs, and the more powerful GPUs use two power connections each. So, adding even a second powerful GPU would require Y power connectors and may overload the MacPro's power supply. (3) All of my 2008 MacPro 3,1 computers sit underneath desks. This can create heat buildup and uncomfortable work conditions for the user. In fact, the area near my desk is 5 degrees warmer than the rest of my office and overall my office is approximately 5 degrees warmer than anyone else's in my area of the building. That's nice in the winter, but in the summertime here in Alabama, it can border on oppressive.

The good news is I am slated to take delivery of another 2008 MacPro 3,1 this weekend. I hope to have it set up by the middle of next week. I retasked one of my mac minis, so I really need to get this done ASAP - I need the MacPro to drive a gel and blot documentation system in my molecular biology laboratory.

Aha I see.... too have only one gpu in most of my machines, I do have two in one machine, and my basement is in the mid 80's even in the Winter time. It is nice in the Winter, I live just South of Washington DC, but not so nice right now. I have a whole house a/c going and a floor model a/c unit running in the basement just to keep it where it is.

Well, folks, I set up my "new" 2008 MacPro 3,1 (OS X 10.8.5, dual 3.0 GHz Quad Core Xeon processors, 12 GB RAM, 1 TB conventional HD, 2 DVD-RAM, AMD HD 5770 GPU, NVIDIA 8800 GT GPU). The molecular biology software and connections will have to wait for Sunday (after the AU and UArk football fans leave town), but I have installed BOINC and C@H and am testing to see whether the configuration is stable. So far, so good. And, as far as I can tell, it will be good for about 140K BOINC credits/day. That's helping me to maintain my RAC while I try to sort out some stability problems with one of my other 2008 MacPro 3,1 units. At first glance, it looks like some rogue Rosetta@Home work units were playing havoc with that unit's dynamic memory allocation - suddenly a Mac that was running little except BOINC started consuming 60-70 GB of memory (combination of RAM and virtual memory), causing all of my applications (including BOINC) to crash. I believe that I have aborted all of the responsible R@H work units, but the 48 hours of instability caused my RAC to drop almost 10%. Ugh. Fortunately, things appear to be trending in the right direction.

Yeah sometimes despite our best tweaking the projects themselves release stuff that doesn't work quite right, it happens at all projects and is frustrating. But satisfying when they get it right again.

What a great Labor Day weekend - AU whips UArk on the gridiron, I set up my Nike+ account to recognize my new Fuelband AND my iPhone-based pedometer, the lawn is mowed, the sidewalks are edged, I rekeyed two locks on my house, I donated some household goods to a friend, I moved my 2008 MacPro 3,1 out of my office and into my molecular biology lab, and my C@H RAC is slowly approaching 800K. All that is left is to grade some papers, prep for class tomorrow, pay my beginning of the month bills, and wade through 100+ email messages. Woo-hoo!

Yeah, Mikey, to some extent I envy the freedom that retirement must be giving you. On the other hand, my job is both fulfilling and a decent source of income - hard to beat that combination! Being around young people helps me to feel young, too!

Oh I LOVED going to work when I worked too, I was a paid f/f for 24 years. It's just that retirement lets me do the things I never could when I was working, like going away for this past holiday weekend and leaving on Thursday and coming back on Tuesday to miss all the 'normal working' people on the roads. Driving in traffic is okay, it's just ALOT more fun not to have too!! AND it's ALOT less stressful after the first couple of years, the first couple of years after you retire people sill be asking for little chunks of your time, after all you now have 'plenty' right?! Once you get past the first couple of years you feel more comfortable saying NO and your time becomes your own and life slows down and all of a sudden you realize how stressful your 'normal' life really was. It IS stressful getting up every day in time to make sure you aren't late for work, making sure you look presentable, don't smell funny, etc, etc, ETC. Once you retire you can get up when you want, have no one to impress besides your spouse, or pet as the case may be, and life IS good again.

Don't get me wrong without the YEARS of working, none of the 'retired' lifestyle is any different, so you gotta pay your 'dues' to really enjoy the retired life.

I have no idea what happened, if you want I can declare you the winner, we ARE the only two playing right now, and just end this. The 'event' that I picked for the games end has not come yet, but if no one plays what's the point.

Sometimes it is nice to know there is someone out there, waiting.

My wife and I have been on penny-pinching duty for weeks as we had a few financial shocks. This has gone right down to investing in one of those gadgets that gives real-time monitoring of electricity usage (bought out of my birthday money!) (49 years old and I get birthday money!!) (well, a gift voucher, actually, from my mother-in-law!!!) (by the way, never buy an American Express Gift Card: nobody takes them) (except the outfit that sold me the real-time electricity monitoring gadget) (for rather more money than the other sites that sell the same gadget).

I had to turn off all processing that relied on the GPU and anything that made the processor run hot causing the big fans to start up.

Since that included the Collatz Conjecture, it felt very wrong to post in this thread. I've been lurking, but not posting.

Also, summer came and visited and brought death-defying temperatures. I know the rest of the world would call these double-digit centigrade numbers "pleasantly cool", "night-time" or "early spring morning" but over here they are intolerable 'cos we're not used to it. And since my GPU can actually warm up this room on its own, it had to go off anyway.

So I've not really posted — just checked in, signed the register, pinched a slice of cake off the table, put some personal post in the out-tray for franking, stolen some stationery, made sure my out-of-office was still on and scuttled off out again.

Note how I didn't bother signing out.

Byeee!

Playing a game is not related to crunching for me, I just like to play. There are several projects I play for but no longer crunch for, or don't crunch for right now, Collatz being one of them. I have NOT quit on Collatz, just right now I have higher priorities, it will be here when I come back. As for temps I understand high temps, my basement is 88.9F RIGHT NOW!! That is with BOTH a whole house a/c running AND an a/c unit running just in the basement! It is just fricking hot in my basement right now, hot enough that I am considering an exhaust vent in the computer area and putting a hole in the wall!!

Oh and I ASK for money for my birthday and Christmas, they are 2 days apart in my case, because that way I can buy what I want, not what someone thinks I might want. I too get gift cards, which I usually exchange with my wife for cash on the way home, so I can get what I really want. We do Christmas at my sisters place because she thinks it is better, which works for me because then my house isn't a mess afterwards like hers is. 8-))

Been out of town for a few weeks on business and been too busy to post to this thread. (Horrible excuse, I know.) But, this morning I am settled into my office, sipping on coffee, and catching up on correspondence before I walk across the street to the Auburn-Louisiana Tech football game.

SandJ, welcome back to thread. Sorry to hear of your financial challenges. Hope that they are soon resolved to your satisfaction. BTW, my wife and I love to receive gift cards or money for birthdays, holidays, anniversaries, and the like. My wife loves gift cards for Starbucks and a local day spa. I am partial to Apple iTunes gift cards.

FWIW, I encourage everyone, C@H cruncher or not, to post to whatever C@H thread they want. I am quite confident that there are many folks out there, even if they are not currently crunching on behalf of C@H, that have insights of value to the C@H family. Post away! Even if that means that I don't win this game!
